While calculations of the von Neumann entropy have led to most of the insight into holography, it is useful to consider other quantum information (QI) quantities in order to give a more complete picture of the emergence of spacetime from entanglement. For example, von Neumann entropy cannot discriminate between different kinds of multipartite entanglement. In this paper, we will focus on a quantity called the reflected entropy, \(S_R(A:B)\)  [1]}, defined for a mixed state \(\rho _{AB}\)  on two parties \(A,B\) . \(S_R(A:B)\)  is simply defined using a canonical purification \(\left| \sqrt{\rho _{AB}} \right>\)  interpreted as a pure state on the Hilbert space of linear matrices, a familiar operation in the context of going from the thermal density matrix to the thermofield double state [2]}. This Hilbert space hosts a doubled/reflected copy of the \(A,B\)  parties and \(S_R(A:B)\)  is defined as
\(S_R(A:B) \equiv S_{vN}(\rho _{AA^\star })_{\mathinner {|{\sqrt{\rho _{AB}}}\rangle }},\)
